Screw retained crown

During the healing phase the dental implant is covered with either a cover screw or a healing abutment. Generally I prefer to carry out dental implant treatments using a one stage process. The one stage procedure means that the dental implant is placed with a healing abutment attached immediately following surgery. This is advantageous from the point of view that the gum will grow around the healing abutment and not cover it. This simplifies the impression appointment and also ensures that no anaesthetic is required. The gums become moulded around what is to become the a tissue collar around the future dental implant crown.

 

Impressions are taken of the dental implant, the part of the implant which is seen here is known as the platform of the dental implant. This particular platform is 4.5mm wide and there is an internal hexagon to reduce any micro movements of the implant crown during function

 

 

 

 

 

The hex tool is showing that there is access to the abutment screw. This is beneficial for several reasons. The access hole allows us to access the screw which removes the crown at any stage. Also no excess cement will be found under the gum tissues. Excess cement under gum tissues can cause tissue inflammation, infection and eventual implant failure.

 

 

The screw retained crown is position. One can only vaguely see the access hole which has been covered by tooth coloured dental cement
